Thymeleaf: How to use boolean operator in JavaScript using Thymeleaf
exception, java, javascript, thymeleaf
Solution
wrap the if block with `<![CDATA[` block
<script type="text/javascript" th:inline="javascript">
var a =b = true;
/*<![CDATA[*/
if(a && b){
alert('Yea');
}/*]]>*/
</script>
Problem
I am using thymeleaf, in javascript using `th:inline="javascript"`, but when we add Boolean conditions in java script thymeleaf thow an exception as below: ``` org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 22; The entity name must immediately follow the '&' in the entity reference. com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203) com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177) com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:441) com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:368) com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1436) com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEntityReference(XMLDocumentFragmentScannerImpl.java:1845) ............................. ``` Below is my javascript code: ``` <script type="text/javascript" th:inline="javascript"> $(document).ready(function(){ $('.fancybox').fancybox({ 'width' :'623px', 'maxHeight':'156px' }); var catId = $("#category").val(); if(catId != null && catId != ''){ findSubCategories(); /*<![CDATA[*/ var subCatId = /*[[${searchProductDto.subCategory}]]*/ /*]]>*/ debugger; if(subCatId != null){ $("#subCategory").val(subCatId); } } }); ............................... ``` how we use & operator in thymeleaf?
